GASOLINE-DISPEN SING DEVICE.

Appneauon med April s,

Our invention relates to devices for d ispensing gasoline, of the visible or gravity eed type in which the liquid is drawn into an overhead vessel 'and then fed to the customers tank by gravit lt is our object to is simple and effective for delivering, 1ndicating and recording any desired amount of gasoline, 'from a device of the general .type notedv above.

. The particular structure of `our invention is based on the mode of dispensing gasoline in which the liquid is drawn into the overhead tank by means of di'ferential air `pres sure, either Jforcing or drawing the liquid into the tank, and a level-is-then established by means of the fill pipe acting to drain away any excess over the predetermined level.

Itis our object to provide a fixed fill pipe,

which alternately acts to lill the tank and then drain away any excessV over its top level. It is our object to provide a movable delivery control pipe. the position of which with relation to the level of the top of thel till pipe, will determine the amount of liquid fractional amounts of gasoline to give a'v that .Hows away.

Another object is to provide for means whereby the delivery control pipe serves as a valve` to direct the liquid flow, selectively from the reservoir to the tank and from the tank to the delivery liose. We desireto accomplish this without rotary motion, and to provide for 'a full, free flow of the liquid when being delivered. v

It is further our obj ect to provide that the motion imparted to ,the delivery control' -pipe and sleeve valve element, shall also be used to-operate a recording and an indicating element, which indicating element can be read in terms of liquid measure and in terms of price also, due to the fact that the price in round numbers, can readily be determined by our device. y i

We have had to provide for means whereby the necessary movement of the moving delivery control pipe, that is required for it to act as a selectivevalve, will not affect the register that gives total quantity dispensed.

rovide a device which 'our 1924. Serial N0. 705,319.

We accom lish our various objects above outlined by t at certain construction andarrangement of parts to be hereinafter more specifically pointed out and claimed.

, In the drawings:

Fi ure 1 is a central .vertical section of evice.

Figure 2 is a section on Fi re 1.

igure 3 is a central vertical section through the pipes that lie in the gravity tank, taken at right angles to Figure 1.

the line 2--2 of Fi ure 4 is across sectlon throu h a modii fied evice for operatin the rac Figure 5 is a lon tudinal section throughV the fixed and mova le (pipes.

We have shown as in icating a casing, the shell 1,.terr`ninating in a late 2 at the top of which is set the air tig t tank 3, preferably of glass. We have not shown amy meansy for setting up low pressure in the overhead tank, as there are a4 number of acceptable ways of accomplisihng this, known in the art. l

, The liquid comes into the tank through a pipe 4, and passes out to the customer through a pipe 5.A Thesetwo pi es are screwed into a main4 stand pipe 6,-w ich ex'- tends from the base of the mechanismup into the tank, to a height which will determine the up er level of liquid in the tank, when same is lled. This stand pi e which is shown as sectional, has a port i) pipe 4 and a port 8 for the pipe 5.

The inner pipe 9, heretofore termed the i for the delivery control pipe, is provided with aplug 10 -to close it at the bottom. It slides inthe stand pipe, and it is provided with a port 11 to register with the inlet port 7 and with an elongated port 12, to register'with the port 8, during the full length of its movement.

` We have shown the upper section of the stand pipe as a separate tube 13, fitted into the main stand pipe, but it will be understood that this is done for'manufacturin convenience. The portion 13 of the stan pipe extends through the plate 2 into the tank and has an elongated port 14, extending from the -base of the tank, to appoint near the 00 rthe port 8, and liquid will fiow through port top of said pipe portion. This port 1 4 does not register with the long port 12 1n the inner sliding pipe.

To move the sliding pipe a rack 16 isV mounted at its lower end and the stand pipe is provided with a boss 17 in which is arranged a spur gear 18 which meshes with the rack. The shaft of this spur gear (suitably packed) passes out through the boss where it is equipped with a sprocket and chain 19.

The to of the pipe 13 is cut away to the level of t e upper end of the port 14 therein. The port 12 in the sliding pipe is so formed and placed that it comes in line with the cut-away end of the fixed ipe, and the ports 11 and 12 are so spaced t at when the port 11 is in position of opening into inlet port 7, then the top end of port 12 is above the cut--away side of the pipe 13, so that liquid level can be established by pipe 13, which liquid level will be the same as the top of the port 14 in said fixed pipe element.

When the port 12 has been moved fa enough down so that it comes below the cut-away edge of the pipe 13, then the port 11 will have passed, beyond port 7, and port 12 will have opened into port 8, thereby permitting liquld to flow out through the pipe 9, to the customers tank.

Thus the operator will first move the sliding pipe up to its upper `osition. He willV then set into operation t e air exhausting system, to draw liquid up through port 7, pipe 9, and into the overhead tank. When the tank is filled to at least the level of the port 14.in the fixed pipe, and the cut-away top edge of said pipe, 'the operator will shut off the air system, and permit the level to be lestablished by holding the sliding sleeve where it is, until the liquid drains back down through port 12 into pipe 9, and thence out through ports 11 and 7. f

It will be assumed that the liquid level so yestablished will be five gallons.

The operator then moves the pipe 9 downwardly, to a point which the indicator (to be described) will show is the amount of gasoline desired. This motion brings the top of the pipe`9 below the top of the port 14, in the fixed pipe 13, and it will also bring7the valve port 11` away from the port -As the port 12 extends above port 14 at full tank period, in raising the pipe 9 the valve formed by ports 7 and 11 will close before the port 14 is opened. In lowering thefpip 9 the port 12 will then open into 14 into pipe 9 over the top and out through port 12, through port 8 and into the delivery pipe. y

As the size of these lengthwise ports can be made as wide as desired within the limits of the sizes of the pipes, a full and free delivery `of gasoline can be provided. The level of the top of pipe 9l will define the amount of liquid which will fiow out through the delivery pipeto the customer.

There are no rotary parts to be found, and the operation of forming, assembling and operating the device as so far described, is very simple and inexpensive.

The distance necessary for the pi e 9 to move prior to closing the valve t rough ports 11 and 7, is provided for at the top of pipe section 13, bythe position of the top of port 12 with relation to the cut-away side of the top of the said pipe section 13.

Any liquid which escapes past the pipe 9 and flows down into the stand pipe, will be trapped and heldthere, by the packed joint 6 for the end of the bar, that mounts the operating rack for the pipe 9.

The devices for indicating and registering the amounts of liquid dispensed, are provided for as follows: Around the stand pipe is journaled a sleeve 20. This sleeve carries a beveled gear 21, and at its upper end carries an indicator wheel 22.

The operating crank or handle 23 is mounted over a shaft 24, having a beveled gear 25 thereon which meshes with the gear 21 and drives it around. This shaft 24 has also a sprocket 26 thereon, from which a chain runs to the rack operating sprocket 19.

Mounted on any suitable bracket within the casing is a beveled inion 27, loose on a shaft-28. The pinion as a conical inner. face, which engages with a like face on a collar 29, keyed to slide but not rotate on the shaft 28. A spring 30 bears between the collar and a ratchet wheel that is fast on the shaft 28.

The shaft 28 drives any suitable register counter mounted in the casing 31. There is a pawl 32 on the casing which prevents the ratchet wheel and hence the shaft 28 from turning except in one direction.

The pinion 27 meshes with the beveled gear 21, and is driven by it, and drives the shaft 28 through the friction clutch formed between it and the conical ,face on the sliding collar onsaid shaft, said collar being pressed to frictionengagement by the spring. When the pinion revolves in the direction in which the shaft 28 cannot turn, the clutch mechanism will slip.

To take care of the necessary valve closing movement during which the pipe 9 does not cause any outflow of liquids to the 'delivery pipe, so that this'movement does not show on the register, we have made the following provision x-The sliding collar 29 last above noted is formed 4with a groove 40. On the under side of the indicator wheel is mounted a curved cam plate 41, whichy depends from the wheelto a position of engagement with the groove in the collar. l The ends of the cam plate are beveled off, so that they will come into engagement with the collar, and during the delivery movement of the pipe 9, the cam will force outwardly the collar on the shaft 28, and thus break its frictional connection withthe conical recess in the face of the loose pinion 27 on said'shaft. The inertia of the register will prevent its operation durin this period. To take care of the non-effective delivery movement of the indicator wheel, the indication marks thereon will be arranged to make no showing until the top of pipe 9 has reached the top of the port 14 in the fixed pipe section.

.The reason for arran ing for this free play, instead ofV merely eginning the slot' 14 several inches below the top of the pipe 13, is that the last noted arrangement would prevent measuring off a quart or so ofthe liquid at the start of the movement of the4 pipe 9. It is evident that pipe 13, Figure 3, could be finished off without the cutback portion, and the top of the port 14 therein left as it is, `whereupon the first inch or so of movement of pipe 9 would have no results until the top of pipe 9 came opposite the top of port 14, whereupon gasoline representing the depth from the top of pipe 13 to the top end of its vport 14, would fiow out, without further movement of pipe 9. No intermedi# ate portions, however, could be measured. Thus the device for inhibiting the register would not be required in this last noted arrangement, as has been noted.

Thus inthe modification 50 is the casing of the device and 51 the stand pipe. The boss or projecting stand pipe' portion 52 ,serves as a central journal yfor the shaft 53,

which is driven by an operating handle 54.- A gear 55 on the shaft within thecasing proiect-ion meshes with the rack 16 connected to the rod that carries the sliding pipe element.

The shaft 53 has a gear 56 Aat its end beyond the middle of the casing which meshes with a gear 57 on the supporting shaft of the indicator drum 58. The casing is provided with a projection 59, open at the top i for view of'the indica-tor drum, which .by

, lyreduces the expense of the provision for gear reduction noted will revolve once forabout five steps of the rack 16.

' 4The totalizer'counter device may be set in a housing 60, and be driven by a pawl ratchet,

the outer edge of which is shown at-61.l The portion 61 is driven by a pinion on the shaft 53.

It may be' noted -that this structure greati measuring the first "few quarts of liquid.

The two pipes within the tank may then be formed as shown in Figure 5, in which the outer pipe or fixed pipe 62` has the long port 63, terminating at the upper end, far enough below the top of the pipe to permit the inner pipe to move-to position of closing the port 7, and opening the port 8 tothe interior of the said sliding pipe, before the upper edge of the sliding pipe reaches the top of the said port 63. The sliding pipe. 64 has the same structure as before, except that the long port 65 therein, lneed not terminate so near the top of the pipe. This gives better Strength to the pipe, and cuts down chance of the slidingpipe developing a split down from the top. c
